There’s good and bad news for motorists now that Jersey City has installed 48 new parking meters along Montgomery Street.

The good news: you can use coins or a credit card to pay at each meter, and you won’t have to run back to your car to put a receipt on your dashboard.

The bad news: sensors will zero out the meters when a car leaves a spot, meaning no more piggybacking on the previous parker’s quarter.

The new meters, located along Montgomery between Warren and Greene streets near the Waterfront, are on a 90-day trial period, with city officials saying they will see after three months whether they should install the meters in other parts of the city.

The meters have been fully functional for the past two weeks.

Mayor Jerramiah Healy said in a press release the meters are an effort to "provide more efficient and convenient parking alternatives" for residents, businesses and visitors.

“We encourage our residents and visitors to use these new meters and provide feedback so we can further improve our parking meter system throughout the city," Healy said.

The city will incur no new costs for the meters, which are simply the old parking meters with new heads and mechanisms, during the trial period, said city spokeswoman Jennifer Morrill.

Parking Authority Executive Director Mary Paretti said the meters have a four-hour maximum limit, up from two hours. The parking rate is now the same for coin or credit-card usage, but there could be a fee in the future for using a credit card, Paretti said.
